Data Repeater Put Error for duplicate

Unknown

Hi,

I have a data repeater and currently have a multiple data from a simple database. I want it to show an error message or limit the selection of the user that when it already input equal data in previous rows, it cannot input it in the next rows

Hey Ezra!

This can be done using Active Form Flows in version 7+, or alternatively using Validation Flows.
[ul][li][url=https://documentation.decisions.com/docs/validation-active-form-flow-and-visibility-active-form-flow]Active Form Flows[/url] (Recommended for Version 7+)[/li][li][url=https://documentation.decisions.com/docs/form-validation-flow]Validation Flows[/url][/li][/ul]
We can build logic that will take in a list of items inputted into the Data Repeater and evaluate them against themselves using the [i]String is in List[/i] default rule.

Ive attached an example project that shows this behavior using a Validation Flow and a Data Repeater with string entries.

Let me know if you have further questions!
